-= UI, Window, and Panel Content
-
-The [classname]#UI#, [classname]#Window#, and [classname]#Panel# all have a
-single content component, which you need to set with [methodname]#setContent()#.
-The content is usually a layout component, although any component is allowed.
-
-
-[source, java]
-----
-Panel panel = new Panel("This is a Panel");
-VerticalLayout panelContent = new VerticalLayout();
-panelContent.addComponent(new Label("Hello!"));
-panel.setContent(panelContent);
-
-// Set the panel as the content of the UI
-setContent(panel);
-----
-
-The size of the content is the default size of the particular layout component,
-for example, a [classname]#VerticalLayout# has 100% width and undefined height
-by default (this coincides with the defaults for [classname]#Panel# and
-[classname]#Label#). If such a layout with undefined height grows higher than
-the browser window, it will flow out of the view and scrollbars will appear. In
-many applications, you want to use the full area of the browser view. Setting
-the components contained inside the content layout to full size is not enough,
-and would actually lead to an invalid state if the height of the content layout
-is undefined.
-
-
-[source, java]
-----
-// First set the root content for the UI
-VerticalLayout content = new VerticalLayout();
-setContent(content);
-
-// Set the content size to full width and height
-content.setSizeFull();
-
-// Add a title area on top of the screen. This takes
-// just the vertical space it needs.
-content.addComponent(new Label("My Application"));
-
-// Add a menu-view area that takes rest of vertical space
-HorizontalLayout menuview = new HorizontalLayout();
-menuview.setSizeFull();
-content.addComponent(menuview);
